Justin Bieber's emotional performance at the MTV Music Video Awards got a lot of ladies swooning - apparently, including Selena Gomez!

According to a report, though Selena Gomez wasn't in the audience during Justin Bieber's performance, she definitely watched her ex-boyfriend singing "Where Are You Now" and "What Do You Mean."

"She knew going into the night that Justin was both excited and nervous," a source reportedly told Hollywood Life. "She's happy for him and knows he's relieved that he pulled it off and was true to himself."

According to a report, Selena Gomez left the crowd just before Justin Bieber went on stage.

"She [Selena Gomez] and the rest of Taylor's [Swift] squad took off at the commercial break just before his performance. They didn't return until the Biebs was done," E! News reported.

Some speculated that the Selena Gomez's move was an attempt to avoid the cameras panning to her during the "Baby" singer's performance.

Sources close to Justin's camp are yet to dish out about his reaction to his ex-girlfriend being impressed by his VMAs performance.

Selena Gomez has recently opened up about her past relationship with Justin Bieber in an interview.

"It's difficult for people to separate us. The internet wants to freeze this moment in time and constantly repeat it," Selena Gomez told The Sunday Times, as quoted by Hollywood Life.

"I didn't think I was doing anything bad by falling in love. There's such an emphasis on people being the perfect thing and then destroying them because it's good press. Also throw in the fact that you are a teenager - it makes it more difficult."

Despite calling it quits, Selena Gomez and Justin Bieber are purportedly moving in the same circle.

According to a previous report published back in July, the ex-lovers were allegedly spotted having a good time together and enjoying some PDA in a hotel pool side in Beverly Hills.
